Take a fairly typical household. The assets are a £350,000 home, £120,000 in pensions, £45,000 in ISAs and investments, and £20,000 in savings, which add up to £535,000. The liabilities are a £220,000 mortgage and £8,000 of loans and credit cards, totalling £228,000. Net worth is assets minus liabilities, so £307,000. Notice that property equity, the £130,000 left after the mortgage, is the single largest piece, which is normal for UK households. Pensions are the next biggest store of wealth even though you cannot touch them until pension age, which is exactly why they belong in the tally.
How it is calculated
The calculation is deliberately simple: it sums everything you own and subtracts everything you owe. Assets are grouped into UK-specific buckets, property, pensions, ISAs and investments, and cash savings, so the picture maps onto how British households actually hold wealth. Liabilities cover the mortgage plus other loans and credit-card balances. The difference is your net worth, the single number that tracks financial progress better than income does. Defined-contribution pension pots count at their current value, and a defined-benefit pension can be included at its cash-equivalent transfer value if you have one. Use the value of your home rather than its equity in the property field, because the mortgage is subtracted separately on the liabilities side, which avoids double counting. Tracking this figure once or twice a year shows whether saving and paying down debt are moving you in the right direction.
Frequently asked questions
Should I include my pension?
Yes. Defined-contribution pension pots and the transfer value of defined-benefit pensions are part of your net worth, even though you cannot access them until pension age. Property equity (value minus mortgage) is usually the largest component for UK households.
How do I value a defined-benefit pension?
Ask your pension scheme administrator for the cash equivalent transfer value (CETV). This is the lump sum your scheme would pay to transfer your benefits to another provider, and it is the most practical figure to use for net worth purposes. Be aware the CETV can change each year with interest-rate movements.
Should I include my ISA and investment accounts?
Yes, include the current market value of all ISAs, stocks and shares accounts, and general investment accounts. Use the value shown in your provider portal on the date you are calculating. Fluctuations are normal and you should update the figure periodically rather than trying to track daily movements.
How often should I recalculate my net worth?
Most people find that once or twice a year is enough to track meaningful progress. Quarterly reviews are useful if you are actively paying down debt or building an emergency fund. Avoid checking too frequently as short-term swings in property or investment values can be misleading.
